Abstract
An emitter electrode is cooled by a cooler to generate condensed water which is charged by a high voltage applied between the emitter electrode and an opposed electrode and is discharged as a mist of charged minute water particles. A controller is provided to vary a temperature drop to a predetermined minimum temperature in dependence of an environmental temperature detected by a temperature sensor. The temperature drop is made variable in proportion to the environmental temperature. Accordingly, a sufficient amount of water can be condensed on the emitter electrode simply by controlling the cooling of the emitter electrode without relying upon an environmental humidity.
